COUPLING.

T 0 all whom it may concern:

Be it known that we, MARTIN NEWMAN, 2d, and N. C. WHrrooMB, of Lanesboro, Susquehanna county, and State of Pennsylvania, and G. C. COLE, of the city of Hartford, in the State of Connecticut, have invented certain new and useful Improvements in the Mode of Attaching and Coupling Wagon Thills and Tongues to the Axles; and we do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying k drawings, forming part of this specification,

in which- Figure l is a side elevation showing the principal parts. Fig. 2 is a side view showing the parts connected. Fig. 3is a View of the coupling pin.

Similar letters of reference indicate corresponding parts in each of the several figures.

The nature of our invention consists of a draw iron: either wrought iron or malleable iron or any metallic substance, so constructed that it will make a safe and. convenient coupling for coupling thills and tongues or poles to the axles of wagons and vehicles of all kinds. The draw iron is formed something after the usual style furnished with a spring bolt orspring button, so arranged that the coupling pin is secured from dropping out or getting out accidentally by the spring button being placed firmly over the head of the coupling pin and secured in this position by the action of the spring on a notch or catch. The spring bolt or spring but-ton has a swinging motion on a center pin which brings the button in position to retain the coupling pin or to withdraw it, as the case might require, either for coupling or detaching thethills or tongues with facility and making the coupling secure against accidental detachment, and is more fully explained as follows.

A represents a transverse section of the axle secured to the draw iron by the clip or clasp B passing over the axle and fastened by the nuts 0, c.

D represents the draw iron and Cr represents the hole through which passes the coupling pin shown in Fig. 3.

button.

I represents the spring portion of the.

bolt or button.

J shows the center pin on which the spring bolt swings to and from the pin hole G. p

S shows a lip or catch which retains the button in its place over the head of the coupling pin as seen in Fig. 2.

F represents a portion of the thill with the eye to correspond with the hole at G through which the coupling pin passes to couple the thill and draw iron together.

Fig. 1 shows the parts disengaged with the coupling pin at Fig. 3. Fig. 2 shows the parts coupled together, the pin being under the button H as seen by the dotted circle in Fig. 2.

The operation of this coupling is as follows: In Fig. 1 the thill is shown as being detached. To couple the thill to the draw iron the eye of the thill is brought back in such a position that it will correspond to the hole in the draw iron. The coupling pin is then passed through the draw iron also through the eye of the thill, and then the spring I is brought over the lip or catch S, as seen in Fig. 2. This brings the other portion of the spring button H over the head of the coupling pin and secures it firmly in its place without the use of either nut or key. To detach the thills or tongue, raise the spring I above the catch S, swing around the spring button H, I to the position shown in Fig. 1, withdraw the bolt and the thillor tongue is detached.

What we claim as our invention and desire to secure by Letters Patent is p The application of the spring but-ton operated in the manner and for the purpose substantially as herein set forth.
